PURPOSE: To prevent dust from being generated on an operating seat by arranging a plurality of supports vertically around the operating seat having a working robot, and by erecting air jetting members for jetting air to the lower side, on upper sections between the supports.
CONSTITUTION: On a truck 12, via the elevating mechanism 13 of a pantagraph type, a service base 14 is elevatably supported, and on the rear of the service base 14, a robot 15 for spraying fire-proof stuff is mounted. Then, at four corners on a rectangular section with the center of the chair 16 of the service base 4, supports 21 are arranged removably and vertically, and on the upper sections of the supports 21, a roof 22 is removably set. After that, with the roof 22, a top plate 24 and an air curtain device 25 are combined, and on the periphery of an operator D, air is jetted from the upper section with the air curtain device 25.
